Answer 2

Arrays: print_r() , var_dump()
JSON: json_decode()

Answer 3

To conveniently view large arrays, I display them like this:

<? echo 'var my_beauty_object = JSON.parse(`'.json_encode($my_big_array).'`);<br>console.clear();<br>console.log(my_beauty_object);'; ?>

then received in the chrome developer console and I get a beautiful collapsible / expandable json object
